1. Kukurumidza Kucheka
Vatengi vazhinji pavanobvunza nezvemuchina wekucheka nelaser vanobvunza kuti muchina wekucheka nelaser unogona kucheka nekukurumidza zvakadii. Zvechokwadi, muchina wekucheka nelaser unoshandisa michina inoshanda zvakanyanya, uye kumhanya kwekucheka ndiko kunonyanya kutariswa nevatengi. Asi kumhanya kwekucheka nekukurumidza hakutsananguri mhando yekucheka nelaser.
Kukurumidza zvakanyanyaakacheka kumhanya
a. Handikwanise kucheka zvinhu zvacho
b. Nzvimbo yekucheka ine tsanga dzakachekwa, uye hafu yepasi pechinhu chebasa inogadzira mavara anonyunguduka
c. Mupendero wekucheka usina kunaka
Kukurumidza kucheka kunononoka
a. Kunyunguduka kwakanyanya kana nzvimbo yekucheka yaomarara
b. Mupata wakakura wekucheka nekona yakapinza zvinonyungudutswa kuita makona akatenderera
Kuti michina yekucheka nelaser iite basa rayo rekucheka zviri nani, usangobvunza kuti muchina welaser unogona kucheka nekukurumidza sei, mhinduro yacho inowanzova isina kururama. Asi, ipa MimoWork ruzivo rwezvinhu zvako, uye tichakupa mhinduro ine mutoro.
2. Nzvimbo Yekutarisa
Nekuti huwandu hwesimba relaser hune simba guru pakumhanya kwekucheka, kusarudza urefu hwefocal lens chinhu chakakosha. Saizi yelaser spot mushure me laser beam focusing inoenderana nehurefu hwefocal lens. Mushure mekunge laser beam yatariswa nelens ine urefu hupfupi hwefocal, saizi yelaser spot idiki kwazvo uye huwandu hwesimba panzvimbo yefocal hwakakwira zvikuru, izvo zvinobatsira pakucheka zvinhu. Asi dambudziko rayo nderekuti neurefu hupfupi hwefocal, pane mukana mudiki wekugadzirisa ukobvu hwechinhu chacho. Kazhinji, focus lens ine urefu hupfupi hwefocal inonyanya kukodzera zvinhu zvakatetepa zvekucheka nekukurumidza. Uye focus lens ine urefu hurefu hwefocal ine hurefu hwakafara hwefocal, chero bedzi iine hurefu hwakakwana hwesimba, inonyanya kukodzera kucheka workpieces dzakakora senge furo, acrylic, nehuni.
Mushure mekuona kuti ndeipi lenzi yefocal length yekushandisa, nzvimbo yefocal point pamusoro peworkpiece yakakosha zvikuru kuti ive nechokwadi chekuti kucheka kwakanaka. Nekuda kwesimba rakawanda panzvimbo yefocal, kazhinji, focal point iri padyo kana pasi zvishoma peworkpiece painocheka. Mukuita kwese kwekucheka, chinhu chakakosha kuve nechokwadi chekuti nzvimbo yefocal neworkpiece inogara iripo kuti uwane mhando yekucheka yakagadzikana.
3. Sisitimu Yekufemera Mhepo & Gasi Rekubatsira
Kazhinji, kucheka nelaser yechinhu kunoda kushandiswa kwegasi rekubatsira, rinonyanya kuenderana nerudzi nekumanikidzwa kwegasi rekubatsira. Kazhinji, gasi rekubatsira rinoburitswa nelaser beam kudzivirira lenzi kubva pakusvibiswa uye kubvisa tsvina iri pasi penzvimbo yekucheka. Kune zvinhu zvisiri zvesimbi nezvimwe zvinhu zvesimbi, mhepo yakamanikidzwa kana gasi risina simba rinoshandiswa kubvisa zvinhu zvakanyunguduka uye zvakapwanyika, ukuwo richidzivirira kupisa kwakanyanya munzvimbo yekucheka.
Pasi pepfungwa yekuona kuti gasi rekuwedzera rinoshanda, kumanikidzwa kwegasi chinhu chakakosha zvikuru. Pakucheka zvinhu zvitete nekumhanya kwakanyanya, kumanikidzwa kwegasi kwakawanda kunodiwa kudzivirira kunamatira kwetsvina kumashure kwekucheka (tsvina inopisa ichakuvadza mupendero wekucheka painorova workpiece). Kana ukobvu hwechinhu hwawedzera kana kumhanya kwekucheka kwanonoka, kumanikidzwa kwegasi kunofanira kuderedzwa zvakakodzera.
4. Mwero weKufungisisa
Hurefu hwe CO2 laser hunosvika 10.6 μm, izvo zvakanaka kuti zvinhu zvisiri zvesimbi zvinyure. Asi CO2 laser haina kukodzera kucheka simbi, kunyanya simbi ine reflectivity yakakura senge goridhe, sirivha, mhangura nesimbi yearuminiyamu, nezvimwewo.
Mwero wekupinza zvinhu mugomba une basa rakakosha pakutanga kwekudziya, asi kana gomba rekucheka ragadzirwa mukati mebasa, mhedzisiro yegomba iri munyama dema inoita kuti mwero wekupinza zvinhu mugomba uve pedyo ne100%.
Mamiriro epamusoro pechinhu anokanganisa zvakananga kunyudzwa kwedanda, kunyanya kuomarara kwepazasi, uye ganda repamusoro re oxide rinozokonzera shanduko dziri pachena muhuwandu hwekunyudzwa kwedanda. Mukuita kwekucheka ne laser, dzimwe nguva mashandiro ekucheka kwechinhu anogona kuvandudzwa nekukanganiswa kwemamiriro epamusoro pechinhu pahuwandu hwekunyudzwa kwedanda.
5. Nozzle yemusoro weLaser
Kana muromo wemuromo usina kusarudzwa zvakanaka kana kuti usina kutarisirwa zvakanaka, zviri nyore kukonzera kusvibiswa kana kukuvara, kana nekuda kwekutenderera kwakashata kwemuromo wemuromo wemuromo kana kuvharika kwenzvimbo kunokonzerwa nekupfapfaidza kwesimbi inopisa, mafungu emvura anobuda mumuromo wemuromo, zvichikonzera kucheka kwakashata zvakanyanya. Dzimwe nguva, muromo wemuromo wemuromo hauenderane nedanda rakatarisana, zvichiita kuti danda rive rakachekwa mupendero wemuromo wemuromo, izvo zvinokanganisawo kunaka kwekucheka mupendero, kuwedzera hupamhi hwemupendero uye kuita kuti saizi yekucheka iparare.
Kune ma nozzles, zvinhu zviviri zvinofanirwa kutariswa zvakanyanya
a. Kukanganiswa kwedhayamita yemuromo wemuromo.
b. Kukanganiswa kwedaro riri pakati pemuromo wemuromo nepamusoro pebasa.
6. Nzira yeOptical
Danda rekutanga rinoburitswa nelaser rinopfuudzwa (kusanganisira kuratidzira uye kutumirwa) kuburikidza nesystem yekunze ye optical path, uye rinojekesa zvakarurama pamusoro pechinhu chebasa nehukuru hwakanyanya.
Zvinhu zvinopenya zvemuchina wekunze we optical path system zvinofanirwa kuongororwa nguva nenguva uye kugadziriswa nenguva kuti zvive nechokwadi chekuti kana tochi yekucheka ichimhanya pamusoro pechinhu chebasa, mwenje unotumirwa zvakanaka pakati pe lenzi woiswa panzvimbo diki kuti ucheke chinhu chebasa chine hunhu hwepamusoro. Kana nzvimbo yechinhu che optical yachinja kana kusvibiswa, hunhu hwekucheka huchakanganiswa, uye kunyangwe kucheka hakugone kuitwa.
Lenzi yekunze ye optical path inosvibiswa nekusachena kuri mumhepo uye inosunganidzwa nezvimedu zvinoputika munzvimbo yekucheka, kana lenzi isina kutonhodzwa zvakakwana, izvo zvinoita kuti lenzi iwedzere kupisa uye inokanganisa kufambiswa kwesimba remwenje. Izvi zvinokonzera kuti collimation yenzira ye optical ifambe uye zvinotungamira kumigumisiro yakakomba. Kupisa kwe lenzi kuchaitawo kuti focal distortion ipararire uye kutoisa lenzi panjodzi.
Dzidza zvakawanda nezvemhando dzekucheka laser yeCO2 nemitengo
